We construct numerically the minimal surface in AdS spacetime surrounded by the light-like segments, which are dual to the 4, 6 and 8-point gluon scattering amplitudes in N = 4 super Yang-Mills theory. We evaluate the area of the minimal surface in the radial cut-off regularization and compare these areas with the formula conjectured by Bern, Dixon and Smirnov (BDS). These numerical solutions h...

As the field of high-precision applications based on carriers continues to expand, the development of low-cost, small, modular receivers and their application in diverse scenarios and situations with complex data quality has increased the requirements of carrier-phase data preprocessing. A new geometry-based cycle slip detection and repair method based on Global Position System (GPS) + BeiDou N...

We report a joint analysis of positron annihilation lifetime spectroscopy (PALS), dielectric spectroscopy (BDS), and nuclear magnetic resonance (NMR) on cis-trans-1,4-poly(butadiene) (c-t-1,4-PBD). Phenomenological analysis of the orthopositronium lifetime τ(3)-T dependence by linear fitting reveals four characteristic PALS temperatures: T(b1)(G)=0.63T(g)(PALS), T(g)(PALS), T(b1)(L)=1.22T(g)(PA...

Global Navigation Satellite System (GNSS) carrier phase measurement for short baseline meets the requirements of deformation monitoring of large structures. However, the carrier phase multipath effect is the main error source with double difference (DD) processing. There are lots of methods to deal with the multipath errors of Global Position System (GPS) carrier phase data. The BeiDou navigati...

With the advances and modernization of GPS, GLONASS, BDS, Galileo QZSS, multi-frequency multi-system joint positioning has become mainstream navigation. Therefore, it is great importance to perform a comprehensive assessment signal quality performance multi-GNSS. In this work, we used multi-GNSS observation data collected by Multi-GNSS Experiment (MGEX) International GNSS Service (IGS), Hong Ko...

Two new atomic/molecular layer deposition processes for depositing crystalline metal-organic thin films, built from 1,4-benzenedisulfonate (BDS) as the organic linker and Cu or Li metal node, are reported. The yield in-situ but hydrated Cu-BDS Li-BDS films; in former case, crystal structure is of a previously known metal-organic-framework-like structure, while latter case not previous studies. ...

OBJECTIVE To conduct a feasibility and efficacy trial of mindfulness therapy in somatization disorder and functional somatic syndromes such as fibromyalgia, irritable bowel syndrome, and chronic fatigue syndrome, defined as bodily distress syndrome (BDS). METHODS We randomized 119 patients to either mindfulness therapy (mindfulness-based stress reduction and some cognitive behavioral therapy ...

Endoscopic ultrasound (EUS)-guided antegrade treatment for biliary disorders was developed for patientswith an altered anatomy [1–5]. This report describes a case of successful EUS-guided bile duct stone (BDS) treatment followed by direct peroral transjejunal-hepatic cholangioscopy in a patient with Roux-en-Y reconstruction. An 80-year-old woman with a BDS and a history of total gastrectomy wit...

The effect of different culture media with different growth regulator and nitrate/ammonium ratios on split garlic shoots was studied to obtain an optimized micropropagation protocol. Three basal media: MS, BDS and BLM (i.e. BDS modi®ed to obtain a nitrate:ammonium ratio of 35 mM:8 mM) combined with two concentrations of NAA (0.5 or 5 mM) and BAP (1 or 10 mM) were evaluated in three Colorado gar...

ABSTRACT Deuterium fractionation can constrain the physical and chemical conditions at early stage of brown dwarf formation. We present IRAM 30-m observations over a wide frequency range 213–279 GHz singly doubly deuterated species formaldehyde (HDCO D2CO) towards Class 0/I proto-brown dwarfs (proto-BDs). Multiple low-excitation HDCO D2CO transition lines with upper energy level ?40 K are detec...
